Detailed Description

With reference to the attached drawings, the fingerprint lock modular clutch mechanism is arranged in a shell 1, and after the fingerprint lock modular clutch mechanism is assembled on a fingerprint lock, the shell 1 is arranged on the outer side of a door. The clutch mechanism structurally comprises an outer mandrel 51 and an outer clutch head 4 which are coaxially sleeved together, wherein a clutch structure is arranged between the outer clutch head 4 and the outer mandrel 51 and is used for realizing transmission connection or disconnection between the outer clutch head 4 and the outer mandrel 51. The outer end face of the outer clutch head 4 is provided with a square hole which is used for being connected with an outer handle, and the outer handle is pulled to enable the outer clutch head 4 to rotate in the corresponding direction. If the clutch structure is such that the outer clutch head 4 is coupled to the outer spindle 51, the outer spindle 51 rotates together with the outer clutch head 4, and if the coupling is released, the outer clutch head 4 idles with respect to the outer spindle 51. The clutch structure can be a rod-shaped clutch pin 8 which is described below, and can also be a movable clutch tooth, and the clutch tooth is driven by a rotating ring to realize the transmission clutch.

In order to facilitate the resetting of the handle, a resetting mechanism is further arranged in the shell 1, and the resetting mechanism is acted with the outer clutch head 4 and the outer mandrel 51, so that the outer clutch head 4 and the outer mandrel 51 can reset after deflecting for a certain angle. The reset mechanism can be a torsion spring or a tension spring. As shown in fig. 1 and 2, the reset mechanism includes a reset push plate 2 disposed in a housing 1, the reset push plate 2 is folded into an angle, one end of a spring 3 acts on the reset push plate 2, the other end acts on the housing 1, the side surface of the reset push plate 2 abuts against an outer clutch head 4 and an outer mandrel 51, and the spring 3 is used for pushing the reset push plate 2 towards the outer clutch head 4 and the outer mandrel 51. A protruding upper protruding piece is integrally formed on the outer peripheral surface of one end of the outer clutch head 4 facing the outer mandrel 51, a protruding lower protruding piece 52 is integrally formed on the outer peripheral surface of one end of the outer mandrel 51 facing the outer clutch head 4, and both the upper protruding piece and the lower protruding piece 52 are abutted against the reset push plate 2. The upper protruding piece and the lower protruding piece 52 are of non-circular structures, when the outer handle is pulled, the upper protruding piece and/or the lower protruding piece 52 push the reset push plate 2, after the outer handle is released, the reset push plate 2 pushes the upper protruding piece and the lower protruding piece 52 under the action of the spring 3, and therefore the reset of the outer clutch head 4 and the outer core shaft 51 is achieved. The outer core shaft 51 is in transmission connection with a lock mechanism of the fingerprint lock, and after the outer core shaft 51 rotates in different directions, the lock bolt of the fingerprint lock can extend out of the outer side of the lock body or retract into the lock body, so that the fingerprint lock can be locked or unlocked.

The figure shows that the clutch mechanism comprises a rod-shaped clutch pin 8, which clutch pin 8 is arranged elastically in the housing 1 in the radial direction of the outer clutch head 4. The opposite sides of the clutch pin 8 are respectively integrally formed with a protruding portion, so that the clutch pin 8 is in a cross shape, and both ends of the two push springs 10 respectively act on the protruding portions on both sides of the clutch pin 8. A pressure plate 9 is arranged on the outer side of the clutch pin 8 in the shell 1, the pressure plate 9 is fixed in the shell 1 through screws, and the pressure plate 9 is used for pressing the clutch pin 8 and the push spring 10.

The clutch pin 8 is inserted with clearance at one end of the outer clutch head 4 facing the outer spindle 51, and a socket 53 for engaging the clutch pin 8 is provided at one end of the outer spindle 51 facing the outer clutch head 4. The driving motor 7 interacts with the clutch pin 8, so that the clutch pin 8 is connected with the outer clutch head 4 and the outer mandrel 51 to realize circumferential transmission or disconnection between the outer clutch head 4 and the outer mandrel 51. The driving motor 7 is provided with a push head 6, the push head 6 is arc-shaped, and the outer end part of the clutch pin 8 is pressed on the concave arc surface of the push head 6. After the correct fingerprint was gathered to fingerprint collection mouth department on the fingerprint lock, driving motor 7 started, and pushing head 6 stretches out towards separation and reunion round pin 8, and makes separation and reunion round pin 8 stretch into socket 53 in, outer separation and reunion head 4 couples together with outer spindle 51 circumference is fixed, pulls outer handle (generally pushes down outer handle), drives the latch mechanism through outer spindle 51 and realizes opening of lock. The controller of the drive motor 7 may be set such that after the lock is unlocked, the drive motor 7 is reversed, the pusher 6 is moved towards the drive motor 7, the clutch pin 8 is withdrawn from the socket 53, and the outer clutch head 4 is allowed to rotate circumferentially relative to the outer spindle 51.

A toggle structure is provided between the upper and lower tabs 52 for locking the outer spindle 51 by the outer clutch head 4. The dial construction comprises a dial 5 arranged on a lower protruding piece 52, the upper protruding piece being divided into two parts by a slot 43, the dial 5 being normally at the location of the slot 43. The inner part 41 of the upper tab close to the reset mechanism is higher than the outer part 42 facing away from the reset mechanism, and the dial 5 is higher than the outer part 42 and lower than the inner part 41, based on the lower tab 52. When a resident goes out, the locking operation can be performed by the outer handle, normally, the outer handle is pulled upwards, the outer part 42 on the upper protruding piece rotates the outer core shaft 51 anticlockwise through the shifting column 5, and the locking is realized. After the fingerprint lock is locked, the main lock bolt and the latch bolt in the fingerprint lock are inserted into the lock bolt hole in the door frame. When the outer handle is abnormally pulled, the outer clutch head 4 can rotate circumferentially relative to the outer mandrel 51 due to the fact that the clutch pin 8 is not engaged, the inner portion 41 of the upper protruding piece can cross the shifting column 5, the outer handle can be pulled up and down freely, and the lock cannot be unlocked.
